We love this lock!
Love the lock. I can give the housekeeper a temporary code or restrict Times certain people can be in the house. Really cool that you can use both a fingerprint and code. I have noticed that the fingerprint will not read if your finger is slightly cold.

Doesn’t fit most doors in USA
Lock looks very good and it feels like it was made well, but the problem is that it doest work on my American door. My door is with two holes: one for lever hanle and the other one is for dead bolt. I decided to install the lock few months after the purchase and figured out that lock is too big! Seller states that lock fits all doors, but it doesn’t say that the door must be with just one opening for lock! Most of the doors in USA are 2 lock. Now I’m stuck with this beutifull lock and I cant return it because it was past 30 days.....read this before purchasing

Fingerprint doesn't work
I installed the lock. It's heavy duty and sturdy, I setup the administrators with both fingerprints and digits but, I couldn't get it to lock unless I installed the app. The keypad is very sensitive and when you press a digit it will record the same digit twice. Because of that It took a long time to enter in the Administrators. I first set myself up as an Administrator then attempted to setup my husband. His fingerprint wouldn't take immediately. I had to make at least ten attempts for him to get setup. He was setup and both the fingerprints and the digital number were tested. The next day when he tried to unlock it neither his fingerprint nor the digital code would unlock the door. He had to use the key. That is the short version. We tried to find a number to call for help but, there isn't one. All in all it was very painful to setup and I am probably going to return it.

Good biometric lock for the price
The fingerprint reader is a little "iffy" at times. I'd hate to really have to rely on it and it's having difficulties. The number pad is good, but loud, I should try to find a mute option.

Horrable!
This has to be the most frustrating lock I've ever had to deal with. The fingerprint reader only works 5% of the time, and when it doesn't read it right a few times, it beeps and flashes at you for 10 seconds before it will let you try again. Installing it, I had to drill a new hole in the door, and the wire gets smashed during install, so I'm sure this product won't last long. The APP is poorly written, there are VERY confusing directions on how to set up passwords, and admin users. First, you have to reset the lock, and then the first fingerprint to touch it becomes admin. How do you change the codes?? I don't know, How do you change the admin password to add new users in the app? I don't know!! So basically, I just walk people up to the lock, try for 30 minutes to get it to recognize my admin fingerprint, and then I let them pick a code, because... the fingerprint reader suuuuucks. Don't get this lock.

You can use phone to open the door
I have always wanted a password lock. After watching it for a long time, I chose it. It is easy to use. In the future, I don't have to be afraid to forget to bring the key. The quality is very good and heavy.

Nice looking Lock But....
They had to make it difficult for the "Administrator" to set it up. You would think the app on the phone would allow the administrator set up all users. Instead you have to jump through hoops of pressing numbers on the keypad for the menu's. Stupid setup but a nice lock. The fingerprint is not all that if you have callus fingers or cold dry fingers. May not work well in northern zone with cold dry hands. Bluetooth goes to sleep when your trying to set things with phone app. I had to keep it alive by touching the screen.

Connexion bleutooth très long lecteur empreinte digital marche 1 foix sur 5 obliger de recommencer plusieurs fois code pas pratique, la poignet est assez basse et je tape 2 touches a la fois et je recommence plusieurs fois. Au final 1-2 min en moyenne pour ouvrir ma porte 1 fois j'ai mis 5min avant de sortir mon smartphone pour ouvrir la porte, contre 10 seconde avec une clef. Le produit pourrait être très bon, mais il est vraiment trop lent. les Plus : plus besoin de clées et je peux donner l’accès a des gens sur des plages horaire ( si ils arrive a entrée ) Les moins : Digital fonctionne pas bien, bluetooth ram, le pavé numérique est lisse et on ne sais pas quel touche nous tapons même avec le rétro eclairage ( pourtant j'ai des doigts tres fins. ca vas plus vite d'ouvrir ma parte avec une cléf
